Please describe your issue in as much detail as possible:

I'm running Steam under Ubuntu Linux (24.04 with nvidia driver 570 (open)).
Since upgrading to an RTX 5090 (MSI Suprim), nearly all games won't run any more.

On starting the game, it does build the Vulkan shaders OK as normal, but then apparently crashes immediately after when trying to launch the game. (The "play" button in the steam window turns from "stop" back to "play" again almost immediately after the Vulkan shader step, suggesting the game crashed).
If I simply replace the 5090 with my old GPU (3090) (just replace the card, no changes in software or other configuration) everything runs just fine.

NOTE: I've subsequently reinstalled Linux from scratch (this time using Ubuntu 25.04 which comes with nvidia driver 570 installed) and the same problem still exists.

Games that work with the 3090 but don't with the 5090 include No Mans Sky, Portal Prelude RTX, Red Dead Redemption 2 and World of Tanks. The only game in my entire library that I've found that still works with the 5090 is Dwarf Fortress. Perhaps because it doesn't even use 3D?

Steps for reproducing this issue:

1. Install an RTX 5090 and try to run any game that has 3D graphics.
